Summary
Grade 7 looks and behaves like Grade 2 and is used in the same kinds of plant, so mixed lots happen. The small palladium addition is what the buyer pays for.
Test every piece for palladium and keep Grade 7 apart. See Titanium Grade 7 scrap.

FAQ
What is the main difference between Titanium Grade 2 and Grade 7?
Titanium Grade 7 is Grade 2 with about 0.15% palladium added for resistance to reducing acids. Palladium is visible on XRF and is the only practical way to separate them.
Can Titanium Grade 2 and Titanium Grade 7 scrap be mixed?
No. Keep them separate. A melter buying either one needs its chemistry to stay within the grade’s limits, and mixing can mean a re-sort or a different valuation.
